Emamectin benzoate B2 suspending agent and preparation method thereof

Abstract

The emamectin benzoate B2 suspending agent is prepared from the following components in percentage by mass: 1%-15% of emamectin benzoate raw medicine, 3%-6% of a dispersing agent, 1%-2% of a thickening agent, 3%-5% of an anti-precipitating agent, 0.1%-0.3% of a defoaming agent, 2%-5% of an anti-freezing agent, 0.1%-0.3% of a preservative, 1%-2% of an antioxidant and the balance of deionized water. The invention relates to a preparation method of an emamectin benzoate B2 suspending agent. The preparation method comprises the following steps: adding deionized water into a modulation kettle; mixing the emamectin benzoate active compound with the auxiliary agent, adding the mixture into the modulation kettle, supplementing with deionized water, stirring, and uniformly mixing; feeding the mixed material into a shearing kettle for shearing; pouring the sheared mixed material and the auxiliary agent into a sand mill for grinding; and sampling, and discharging after all detected indexes are qualified to obtain a finished product. The product is a biological pesticide which is efficient, broad in spectrum, low in toxicity, low in residue and long in lasting period, has a good killing effect on lepidoptera pests, is pollution-free, is a first choice for agricultural products, does not generate waste gas, waste water and waste residues in the production process, is free of dust harm and is safe to operators and the environment.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation, in particular to a emamectin benzoate B2 suspension and a preparation method. Background technique [0002] Emamectin benzoate, also known as emamectin benzoate, is a high-efficiency insecticide. At present, powders and wettable powders in existing dosage forms have dust pollution, easy photolysis, poor persistence, and are affected by environmental conditions. There are also a series of problems such as humidity, high temperature, and low temperature are very unfavorable to storage, prone to powder agglomeration, and inconvenient packaging and transportation. Therefore, it is necessary to provide a emamectin benzoate preparation that is environmentally friendly, stable in storage and capable of effectively preventing and controlling crop diseases and insect pests. Contents of the invention [0003] The object of the present invention is to provide a kind of emamectin benzoate B2...
